A vulnerability was found in SourceCodester Telecom Billing Management System 1.0. It has been rated as critical. This issue affects the function addrecords of the file main.cpp of the component Add New Record. The manipulation of the argument name/phonenumber leads to buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. Other parameters might be affected as well.
The CVSS score for this vulnerability is 4.8, indicating a medium severity. Organizations should prioritize patching immediately. The risk to organizations includes potential disruption to services and unauthorized access to sensitive information.
As of now, there is no known public exploit available for this vulnerability. However, maintaining vigilance is essential, as local access is required to exploit the issue.
In light of its critical nature, organizations using the affected system should address this vulnerability in their priority patch cycle.
Vulnerability Details
A vulnerability was found in SourceCodester Telecom Billing Management System 1.0, which has been rated as critical. This vulnerability allows for a buffer overflow due to the manipulation of the argument name/phonenumber in the addrecords function located in main.cpp. Local access is required for exploitation. The CVSS score is 4.8, which indicates a medium severity level.
The CWE classifications associated with this vulnerability are CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input).
Technical Analysis
The root cause of this vulnerability lies in improper handling of user input in the addrecords function. Specifically, the function does not adequately check the size of the input parameters, which allows for a buffer overflow.
The attack vector is local, meaning that an attacker must have local access to the system to exploit this vulnerability. The attack complexity is low, as it does not require advanced skills or tools to exploit. Privileges required are low, indicating that a user with standard access can potentially exploit this vulnerability. No user interaction is required.
The impacts of this vulnerability are low for confidentiality, integrity, and availability, but the potential for data corruption exists due to the buffer overflow.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is moderate due to the requirement for local access for exploitation. However, organizations must recognize the potential for significant impact if an attacker gains unauthorized access.
The blast radius for this vulnerability could extend to any system where the Telecom Billing Management System is deployed, potentially affecting sensitive customer information and billing processes.
Organizations should assess the urgency of addressing this vulnerability based on their specific environment, considering that the CVSS score indicates a medium severity level.
